Device for the measurement of speeds and torques and for the simulatio of driving conditions on a driven shaft for a motor vehicle wheel

Abstract

The invention concerns a device (1) for the measurement of speeds and torques and for the simulation of driving conditions on a driven shaft (3) for a motor vehicle with a driveshaft (4) and at least one electrical machine (31), having a rotor (5) and a stator (6), whose rotor shaft (7) is mechanically connected with the driveshaft (4) and which is mechanically coupled via a detachable connection with the driven shaft (3) for the motor vehicle wheel so that they rotate together. The invention is based on the task of making a device of this type with which, in addition to the speed and torque measurements, the flow behavior of a motor vehicle and the sound intensity generation of this motor vehicle can be simulated in a wind tunnel relative to a motor vehicle provided with typical tires. This task is solved according to the invention in that the driveshaft (4) is surrounded by a stator rim (8) located concentrically to it in a way known in and of itself, the stator (6) is attached to the stator rim (8) in a way known in and of itself, and the device (1) has an external circumference with essentially the rotationally symmetrical form of a motor vehicle wheel and is tailored to the wheel housing (9) of the motor vehicle (A).
